Once a "dry" macula is achieved the interval between visits is then lengthened by 2-week increments, at every visit the macula is "dry". IVT ranibizumab will be rendered at every visit, no earlier than 7 days before the target date and no later than 7 days after the target date; the interval between visits is individualized based on each patient's response to treatment. The interval between injections will not exceed 12 weeks
